Innovate and Elevate: the Ispirer tools update

May 10, 2024

The Ispirer team proves every month that improving the quality of conversion is our main trump card. Enriching the core of Ispirer Toolkit is our main goal in order to provide a high level of migration for all directions.

This month we added a whole bunch of conversion rules to our tool (as always). Among the technologies that received the most updates are the following: Informix, PostgreSQL, Visual FoxPro, Sybase ASE, MS SQL Server, Oracle, C++, DB2, Sybase IQ, Firebird.

Ispirer Toolkit has received several important updates. One of them is improving ESQL recognition in source code. Now the tool qualitatively identifies the ESQL contained in the source code to enable a more accurate conversion to the selected technology. What is more, the extraction of constraints for Oracle as a source was modernized so that the tool quickly selects the necessary information.

Assessment Toolkit hasn’t been left unnoticed either. Additionally, for SQL Server to PostgreSQL conversions, we've refined the complexity calculation algorithm for more accurate and quick database assessment.

Besides, the Ispirer experts greatly updated our Java frameworks with the new functionality.
